What is Colour Psychology?

Colour Psychology

Have you noticed that your environment affects your feelings and state of mind? Why do you feel agitated in some places while you feel calm in others? 

The colours at those places might be affecting the way you feel. 

Colours play an essential role in communicating information, influencing moods, and impacting your decisions. And this is where colour psychology enters the picture. 

In this article, you’ll learn what colour psychology is and how colours impact you. 

What Is Color Psychology?

In simple words, colour psychology studies how specific colours impact human mood and behaviour. When it comes to nonverbal communication, mood creation, and even decision-making, colour plays a significant role. 

Since about 90% of our snap judgments are affected by the psychological impacts of colour alone, it is critical to understand what colours mean and the reactions they might evoke. And that is the scope of colour psychology.

Colours are powerful communication tools encourage action and physiological reactions and influence mood. Specific colours are found to have an impact on blood pressure, metabolism, and even eyestrain.

A Brief History of Color Psychology

Sir Isaac Newton examined how a particular wavelength of light determines each colour in the late seventeenth century. He also developed the colour spectrum, and the colour wheel was created by Isaac Newton in 1704. 

Then in the early 20th century, Swiss psychiatrist Carl Jung researched how colour affects the human psyche. Ultimately, Jung created colour therapy, allowing his patients to communicate via colour and imagery. Nowadays, the main applications of colour psychology are marketing, business, and advertising.

Psychological Effect of Colors

There’s no denying a variation in the meaning, interpretation, and perception of different colours in different cultures. But some colours have universal implications.

The colours on the blue side are called cool colours. They include blue, green, and purple. Cool colours are calming and relaxing. However, these colours may evoke feelings of sadness.

Colours on the red side of the spectrum are called warm colours, including red, yellow, and orange. Warm colours evoke many emotions, from happiness and warmth to anger and anxiousness.

Here are some of the standard colours and their psychological effects: 


The symbolic meaning of the colour white is truth and sometimes even indifference. It encourages feelings of safety and cleanliness. Clean, white clothes and linens show sterility since stains are easily visible. That’s why doctors and nurses frequently wear white lab coats and scrubs.


The symbolic meaning associated with the colour red is passion, excitement, and love. It’s the colour of urgency, power, and desire. Red is said to boost hunger and is believed to inspire confidence and excitement. This colour has also been found to increase blood pressure and heart rate. 


The colour blue symbolises wisdom and hope. It’s the colour of peace and confidence. Blue has been shown to reduce blood pressure and pulse rate. It fosters serenity and a sense of belonging.


Yellow is the colour of warmth, kindness, and happiness. It’s often associated with optimism and well-being and promotes energy. 


The colour green symbolises peace, growth, and nature. Green is the colour of success, promoting healing and tranquillity. 


Black is the colour of stability and power, which gives a sense of authority. Thus, the black colour often represents professionalism and expertise.
